Inventure's persistent upper fan error


#1

My Inventure just keeps telling upper fan error after upper fan was replaced, hotend was replaced and extruder cable was replaced.
Can anyone tell me what might be the real problem?

Hi,

The extruder PCB may also be responsible for the problem you are facing. Our support agent already provided you with further information - please, check your mailbox.
